3 To all who m itmay concern:

Be it known that I, CARL PETERSON, a

' ;citizen of the United States, residing at Newcastle, in the county of. Henry and State 1 of Indiana, have invented new and usefulglmprovements in Lid Adjusters and Supports, of which the following is a specification. This invention relates to" improvements in means for holding the hinged lids of --pianos, piano benches, and receptacles of all kinds, at diiferent heights, and the object is to provide a device that will automaticallylock itself the raising of the lid, and to provide a lock which can be 1 released and returned to a closed position 'by raising the lid to a still higher position.

I acc'omplishthe above and other objects which will hereinafter appear, by the means illustrated in the accompanying drawing, in which I Fig. 1, is a view invention removed from a lid and receptacle. Fig. 2, is an edge view of the same. Fig.

'3, is a longitudinalyertical section of a piano bench with the lid raised by means of my invention placed near the outer or free end of the lid, and'Fig. 4 is a fragment of a piano case with the'lid raised by my invention located near the hinge edge of the lid.

Like characters of reference indicate like parts in the several views, of the drawing.

My invention 7 comprises a plate 3 with screw holes by which it is secured by screws to a lid 6, secured by hinges 4 to a receptacle 5; Depending from the plate is an integral ear 7 to which a flattened portion of a hook-bar 8 is pivoted. A leaf-spring 9 is attached atone end to the plate 5 and bears, near its outer free portion, against the end of the hook-bar 8; The end of the bar 8 is flattened in a plane to contact with the spring and hold the bar-proper by the spring pressure, in-contact with the notched edge of a locking-plate 10. The free lower end of the hook-bar is bent laterally in the manner shown in Fig. 2 to form a hook 11. I The locking-pin 10 is oval in general form, with more or less pointed ends to facilitate the shifting from one edge to the other, of the hook 11, and on that edge of the plate which is toward the hinge of the lid a series of notche .12 is provided.

number but they may. be more or less than I that depending upon the "number of positions at which it'is desired to lock the raised" lid. The plate 10 is'secured to the side of I vice near the free end of the' lid, but for supporting the lid of av piano itself, it is best to locate the lid holding device near Iof theseat to suit the convenience ofthe player, it 1s best to place the holding dethe hinge where it will be less in evidence the lid, as shown in Fig. 1 I The operation is the same for all loca-' and afiord a higher range of movement for is such that when pressed by the spring 9 the. bar stands relative to the locking plate 10 when the lid is closed as shown inthe "lower dotted lines in Fig. 3, whereras the lid is raised the hook 11 will follow the notched side of the plate 10 and enter the notches 12 in the regular order by the actionof the spring. The-entrance to the notches slope upwardly to hold the hook against a downward movement, but to allow the hook to raise out of a notch byan upward movement of the lid. Consequently, the lid may be raised until a holding notch at the required height is reached. Then, when it, is desired to close the lid, it is raised until thehook haspassed the upper end of the locking-plate, and thereupon the spring will move the hook to the other side of the locking-plate in the then elevated position of the hookjand by lowering the lid the hook will be returned to the place of beginning.

Should a notch too high be entered by the I over again by first lifting it above the end of the locking-plate and closing the lid and by then raising it to the height desired.

Having thus fully described my invention what I claim as new and wish to secure by Letters Patent of the United States, is-- 1 l 1. The combination of areceptacle having at a normal position, and a locking-plate secured to a Wall of the receptacle, said plate having notches into which the hook on the bar is pressed by the spring upon raising the lid.

2. The combination or a receptacle having walls, and'a lid hinged to one of the Walls, of a lid-adjuster and support comprising a bar pivoted to the lid and terminating at its free end With a hook, spring means for yieldingly' holding the bar at a normal position, and a locking-plate secured to a Wall of the receptacle, said plate having upper and lower tapering ends and downwardly oblique notches in one edge to successively engage the hookloy the action of the spring which presses the hook against the notched edge of the plate as the lid is raised and which causes the hook to pass down along :1. nose-3s the otheredge of" the plate as thelid is closed.

3. The combination of a receptacle having rigid walls and lid hinged to one. of the ivalls, of a-lid-adjuster and support comprising a plate secured to the lid and having an ear a. bar having a flat end pivoted to the ear with a hook at its opposite free end, a leaf-spring on the plate pressing the ad jacent flat end of the bar to hold theloar in a yieldingly normal depending position, and alocking-plate generally oval in shape secured to a Wall of the receptacle With one of its small ends toward the lid, said plate having downwardly'oblique notches in one edge to successively engage the hook 'by the action of the spring, said spring pressing the hook against the notched edge or the plate as the 11d is raised and aganist the opposite edge of the plate as the lid is closed.

Signed at Newcastle, Indiana, this the 3rd day of December, 1921. i CARL PETERSQN.
